The small Paleozoic protozygopteran family Permagrionidae comprises 11 described species in 5 genera from the Lower Permian Chekarda and Solikamsk localities in Russia (Zalessky, 1948; Nel et al., 2012) and Salagou Formation in France (Nel et al., 1999; Fate et al., 2013), the Middle Permian Soyana and Kargala localities in Russia (Martynov, 1932; Martynov, 1937; Nel et al., 2012), and the Upper Permian Bodie Creek Head locality in Malvinas Tillyard (1928). Here we describe the new species, Epilestes rasnitsyni sp. nov. from the Ufimian of Perm Territory, which is characterized by specific arrangement of veins in the petiole and the unique preservation of body structures.

The paper considers a new species of gleicheniacean fern Tumidopteris astra Naugolnykh sp. nov. from the Lower Permian (Kungurian) and the Middle Permian (Roadian) deposits of the Pechora coal-basin, Russia. The new species is characterized both by macromorphology of the fertile and sterile pinnules and micromorphology of the sori and sporangia. Morphology of the most closely related leptosporangiate ferns is discussed.

AbstractA small collection of non-marine lamellibranchs and plants from the Madumabisa Shales of the Gwembi district of Northern Rhodesia is described. It includes a new species of the genus Kidodia, Palaeomutela rhomboidalis, and P. neglecta, associated with Glossopteris indica. The Madumabisa Shales may be correlated with similar beds in Southern Rhodesia assigned to the Tapinocephalus zone of the South African Lower Beaufort Series, and are of Upper Permian age.

In 2004 Watabe and Kaesler published a paper on a new species of the ostracode genus Paraparchites from the Lower Permian of Kansas and named it Paraparchites punctatus. Thereby they failed to notice that already in 1936 a Paraparchites punctatus had been described by Harris and Worrell from the Lower Permian of Oklahoma.

A new species of the sphenacodontid synapsid Dimetrodon, D. teutonis, is described on the basis of a single, adult specimen consisting of a large portion of the presacral vertebral column. The holotype was collected from the Lower Permian Tambach Formation, lowermost formational unit of the Upper Rotliegend, of the Bromacker quarry locality in the midregion of the Thuringian Forest near Gotha, central Germany. This is the first record of the genus outside of North America and, therefore, provides not only additional biological evidence of a continuous Euramerican landmass during the Early Permian, but also the absence of any major physical or biological barrier to faunal interchange of terrestrial vertebrates. An estimated weight of 14 kg for D. teutonis is half that of the smallest, previously recognized species, D. natalis. Sphenacodontid phylogeny indicates that the diminutive size of D. teutonis represents an autapomorphy and is in general accord with the absence of large-sized, basal synapsid predators at this truly terrestrial upland locality. It is speculated that the diminutive size of D. teutonis was probably an adaptation to a truly terrestrial, relatively uplands existence like that represented by the Bromacker locality. Here it subsisted on small vertebrates (and possibly large invertebrates) of the Bromacker assemblage, in which the dominant members in both size and abundance were herbivorous diadectids, and it was unlikely to encounter large predators.

AbstractA foraminiferal fauna in the Lower Permian Marls of the Lowpit Lane Borehole, Derbyshire, included numerous examples of a new species of the genus Aschemonella Brady. This is described as Aschemonella longicaudata sp. nov. and the possible growth form of the genus is discussed.
